What a Car Maintenance App Does

A car maintenance app, or auto maintenance app, does 3 jobs: it tracks your vehicle's service history, sends maintenance reminders by date or mileage, and records fuel, repair and other car costs in one place. Popular auto maintenance apps include CARFAX Car Care, Simply Auto, Drivvo, Fuelly, FIXD and AUTOsist; in Covr's review of the 4 top-ranking comparisons for this search, CARFAX Car Care, Simply Auto, Drivvo and FIXD appear in 100% of them and Fuelly in 75%.

Service History With Mileage

A service history in an app is a dated list of every oil change, tire rotation, brake job and repair, each with the odometer reading at the time. AAA describes maintenance apps as digital tools that track service schedules, fuel costs and maintenance records, and notes that a complete, organized service history can raise a car's resale value. The record goes with you to the shop, to a buyer or to a warranty claim.

Reminders by Date or Mileage

A maintenance app reminder fires when a service is due by time, by miles, or by whichever comes first. You enter the interval from your owner's manual, and the app counts down from the last entry. AAA notes that many modern cars already show service reminders on the dashboard; an app adds a full history and works for older cars that lack the system.

Costs, Receipts and Documents

Cost tracking in an auto maintenance app turns each service entry into a running total, so you can see what fuel, parts and labor cost per car. Many trackers also hold receipts and paperwork: Simply Auto's site lists receipt backups on its paid versions, and MyAutoLog's publisher describes document storage with expiry alerts.

Auto Maintenance Tracker Features

An auto maintenance tracker has 4 key features: service and maintenance reminders, a service history with mileage, cost tracking for fuel and repairs, and reports or exports you can share. Some trackers add receipt photos, document storage, GPS trips or an OBD2 connection, usually on a paid plan.

App vs Paper Log or Spreadsheet

An app is not the only way to keep records: a paper logbook or a spreadsheet with columns for date, mileage, service and cost works too, as Google's People Also Ask answers note. The difference is that software reminds you, while paper only remembers. Covr's separate car maintenance log guide covers printable templates; this page covers apps.

Covr Maintenance History: What It Tracks

The Covr app keeps a maintenance history with mileage and reminders, tracks car expenses and stores vehicle documents on your device, according to its Google Play description.

What You Can Do in the Covr App

The Covr app handles 4 jobs for car owners, and leaves 4 others to different tools:

What Covr Does Not Do

The Covr app does not download a manufacturer maintenance schedule for your model, connect to your car's OBD2 port, read check-engine codes, send recall alerts or book shop appointments. You enter the service intervals from your owner's manual yourself, and Covr reminds you from there. Use a diagnostic tool from the car repair section below if you need those codes read.

Documents Stay on Your Phone

Documents in the Covr app are stored on your device, per the Google Play description. Your insurance card is the proof of insurance that state law in most states requires you to show at a traffic stop, and your registration renewal date is set by your state's DMV, so keeping both in the app saves a search. Check the data safety section of the Google Play listing and Covr's privacy policy for what the app collects.

How Insurance Quotes Work in Covr

Covr is not an insurer and does not issue policies or set prices. When you request quotes, you share your ZIP code and phone number, and partner insurance companies licensed by state regulators contact you, often by phone, with their offers; how Covr works explains the steps before you share anything. For context on what you are comparing, full coverage averaged $2,508 a year in a September 2026 U.S. News analysis. Before you accept an offer, you can check the insurer's license and complaint record with your state's department of insurance or the NAIC.

Start Your Maintenance History

Install Covr from Google Play, add your car, enter your last service with its mileage, and set a reminder for the next oil change. Adding older receipts as past entries builds a fuller history for a future buyer. The home page lists other Covr guides and app features.

Best Car Maintenance Apps Compared

The best car maintenance app depends on how service records reach it: shop reports (CARFAX Car Care), manual entries (Simply Auto, Drivvo, MyAutoLog, Covr) or an OBD2 sensor (FIXD).

Comparison of 7 Maintenance Apps and Covr

According to Covr's October 9, 2026 review of 4 published comparisons (AAA, Carmainty, MyAutoLog's carmaintenance.app and OBDeleven), Simply Auto's website and Covr's Google Play description, 7 of the 8 apps below need no extra hardware, and CARFAX Car Care is the only one that fills in shop history automatically. The table is a compilation of what those sources state, not a hands-on test; Carmainty, MyAutoLog and OBDeleven publish competing products, so check each store listing.

CARFAX Car Care

CARFAX Car Care is free on iOS and Android and tracks up to 8 vehicles, with service reminders, repair cost estimates, past service history and safety recall alerts, AAA reports; AAA lists ratings of 4.8 on the App Store and 4.7 on Google Play. Shops that report to CARFAX add records automatically, but OBDeleven notes those records are not always consistent and the service works only in the US and Canada. DIY work still has to be typed in.

Simply Auto

The Simply Auto app's website lists a free version, a Gold version for a one-time $9.99 and a Platinum version for $9.99 a year, covering up to 4, 7 and unlimited vehicles. It logs fill-ups, services, expenses and automatic GPS trips (15 a month on Free and Gold), and AAA notes it also tracks kilowatt-hours for EVs. OBDeleven's review warns that even a simple fill-up asks for many fields.

Drivvo

The Drivvo app has been downloaded more than 1.5 million times and holds a 4.6-star rating, AAA reports. The free version tracks fuel, services and expenses for several vehicles; cloud sync needs the premium plan. OBDeleven notes that the free version shows ads, every entry is manual, and business plans manage fleets of up to 100 vehicles, including trucks and buses.

Fuelly

Fuelly runs on iPhone (with a web version) and is built around fuel: it calculates your real-world MPG and compares it with community averages for the same vehicle, AAA reports, with a 4.5-star rating. It also handles basic service reminders, but the app is not a full service record.

FIXD

FIXD pairs its Android and iPhone software with a Bluetooth OBD2 sensor that costs $59.99, and its reminders do not work without the sensor, according to OBDeleven's review, which counts up to 15 vehicles per device. AAA lists FIXD at 4.6 stars on Apple and 4.2 to 4.3 on Google Play. It suits drivers who want check-engine codes explained in plain English.

AUTOsist and MyAutoLog

The AUTOsist app offers a free version for personal use and paid plans for fleets, with preventive maintenance schedules, repair tracking, digital inspections and receipt storage, AAA reports. MyAutoLog is free for 1 vehicle on iPhone and Android and records shop and DIY services with reminders by date or mileage, according to carmaintenance.app, a site run by MyAutoLog's own publisher.

Best Vehicle Maintenance App by Need

The best vehicle maintenance app is the one that matches where your car gets serviced and how many vehicles you manage.

• All service at dealers and chain shops: CARFAX Car Care, because participating shops report records for you.
• DIY oil changes and home repairs: a manual logbook such as Drivvo, Simply Auto, MyAutoLog or Covr, which record work no shop reports.
• Fuel economy first: Fuelly or Simply Auto for MPG and fuel cost.
• Check-engine light: FIXD or another OBD2 tool with a plug-in device.
• History, expenses, documents and insurance quotes in one place: Covr on Android.

Fleet Vehicle Maintenance App

A fleet vehicle maintenance app adds many vehicles, several drivers and inspections to the basic service record. Drivvo's business plans cover up to 100 vehicles, according to carmaintenance.app and OBDeleven, and AUTOsist's paid plans target businesses and fleets, AAA reports; those 2 apps make up 25% of the 8 in our comparison table. Covr is built for personal cars, not fleet management, and commercial fleets also answer to federal and state regulations on vehicle inspection records.

Android and iPhone Options

Android and iPhone versions exist for most maintenance apps, but not all: Fuelly is iPhone-only, AAA reports, and Covr is listed on Google Play. CARFAX Car Care, Simply Auto, Drivvo, FIXD, AUTOsist and MyAutoLog run on both. Ratings can differ by store: AAA lists Carly at about 3.5 stars on Google Play against 4.7 on the App Store, where users mention its subscription charges.

Car Service App for Android

A car service app for Android, also called an auto service app or vehicle service app, keeps your service history and reminders on an Android phone: CARFAX Car Care, Simply Auto, Drivvo, FIXD, AUTOsist, MyAutoLog and Covr all list Android versions in the sources above. Check the store rating, the latest reviews and the data safety section before you install.

Best Car Maintenance App for iPhone

The best car maintenance app for iPhone depends on the job: CARFAX Car Care for shop history, Fuelly for MPG, and MyAutoLog, whose publisher says it needs no account on iPhone. Covr's listing is on Google Play, so iPhone owners need one of these instead.

Free Car Maintenance Apps

Free car maintenance apps come in 2 forms: tools that are free outright, such as CARFAX Car Care, and free tiers that limit vehicles or features or show ads.

Free Tier Limits

Free tier limits differ by app: MyAutoLog allows 1 vehicle, Simply Auto allows 4, CARFAX Car Care allows 8 at no charge, and Drivvo's free version carries ads, according to the sources in the comparison table.

Check what you lose before you enter years of data, because exporting those records can be harder than adding them.

No Hardware Needed

A free vehicle maintenance app with no hardware works from manual entries or shop reports alone. OBDeleven's review calls CARFAX Car Care the best free option with no hardware and says it has no in-app purchases; Simply Auto and Drivvo also run without any device.

When Paying Makes Sense

Paying for an app makes sense when you need cloud sync, more vehicles or receipt backups: Drivvo charges for cloud sync, and Simply Auto's Platinum version at $9.99 a year adds unlimited vehicles and unlimited automatic trips. Diagnostic tools add the cost of the device on top of any subscription.

Car Repair Apps: Diagnostics and Mechanics

A car repair app finds out what is wrong with the car or who can fix it, which is a different job from a service record of work already done.

OBD2 Diagnostic Apps

OBD2 diagnostic apps read fault codes through a device plugged into the port under the dashboard. OBDeleven's review lists device prices starting at $59.99 for FIXD, $74.99 for Carista, €64.80 for a Carly adapter and €84.99 for OBDeleven, with extra features costing more; the FIXD sensor costs 20% less than the Carista device.

Google's People Also Ask answers name Car Scanner ELM OBD2, which works with a low-cost ELM327 adapter to read and clear engine codes.

Repair Cost Estimates

Repair cost estimates appear in several tools: AAA lists repair estimates in CARFAX Car Care and FIXD, and OBDeleven notes FIXD shows likely repair costs and nearby workshops after a scan. Treat any in-app estimate as a starting point and get a written quote from the shop; some states regulate auto repair shops and require a written estimate before work begins.

Finding a Mechanic

Finding a mechanic is a third kind of auto repair app. The AAA Mobile App locates AAA-owned Car Care Centers and AAA Approved Auto Repair facilities, and AAA says members get a 10% discount on repair labor, up to $75, at those locations. Google's People Also Ask answers name Auto Monkey for booking mobile mechanics who come to your driveway.

Free Auto Repair Apps for Android

Free auto repair apps for Android include CARFAX Car Care for repair estimates and FIXD's free software, though FIXD code reading needs its $59.99 sensor and Car Scanner ELM OBD2 needs an ELM327 adapter. Covr does not diagnose cars, but you can enter the repair and its cost in your Covr history afterward.

Maintenance Reminders and Oil Changes

A car maintenance reminder is an app alert that tells you a service is due: maintenance apps send reminders by date, by mileage or by whichever comes first, for oil changes, tire rotations and other services. Set both, because a car driven little can need service by time before it reaches the mileage.

Vehicle Service Reminder Timing

A vehicle service reminder from a maintenance app arrives before a service is due, based on the interval you set and on how current that mileage entry is. OBDeleven says its own reminders arrive 30, 7 and 1 day before a service is due, while the Carly Maintenance feature does not send notifications, according to the same review. Many states regulate handheld phone use while driving, so act on reminders when you are parked. A car service schedule guide helps you choose which intervals to enter.

Oil Change Reminders

An oil change reminder is the simplest use of a maintenance tracker or oil change app: note the date and odometer reading at each oil change, and set the next one from the interval in your owner's manual. Oil type and driving conditions change that interval, so do not copy a number from another car. AAA's maintenance checklist adds a monthly look at tires, fluids, lights and the battery, or about every 1,000 miles, which a repeating monthly reminder covers.

What to Record in a Car Maintenance Tracker

A car maintenance tracker, also called a vehicle maintenance tracker or auto service tracker, needs 7 fields for each service entry to be complete, according to Google's People Also Ask answers.

Vehicle Repair Records

A vehicle repair log entry, whether in a car repair log app or a paper auto repair log, needs more detail than a routine service: the problem, the diagnosis, the parts replaced, the shop and the warranty on the work. Keep the invoice too, because a repair warranty claim usually needs that invoice.

Records for Warranty and Resale

A service log protects your warranty: the Federal Trade Commission explains that under the Magnuson-Moss Warranty Act, a federal statute passed more than 50 years ago, a manufacturer generally cannot void your warranty just because you or an independent shop did the routine maintenance. Keep receipts and dated entries that show the work was done on time. A complete record also proves to a buyer that the car was cared for, AAA notes.

How to Choose a Car Maintenance App

Choosing a car maintenance app comes down to 5 checks, made before you enter years of records.

• Where records come from: pick a shop-reporting service only if your shops report to it; otherwise you need easy manual entry.
• Reminders: make sure reminders work by both date and mileage.
• Vehicles and price: count your cars and compare them with each free tier's limit.
• Hardware: decide whether you want diagnostics, which means buying an OBD2 device.
• Privacy and data: read the privacy policy and the data safety section on Google Play or the App Store privacy label, and note which permissions are requested.

Privacy Rules and Permissions

Privacy rules give you some control over the data an app keeps: California's privacy regulations let residents ask a company to delete the personal data it holds, and businesses generally must respond within 45 days. Several other states now have a consumer privacy statute with similar rights over app data. Grant only the permissions a feature needs, such as location for GPS trips, and switch them off when you stop using that feature.

Can You Move Your Data Later?

Moving data between apps is not always possible. Drivvo imports data from Fuelio, Fuel Log and aCar, carmaintenance.app reports, and MyAutoLog imports data on request through support. Ask about export before you commit, and keep copies of important receipts outside any single service.
